Abstract
A distributed radio access network (RAN) includes a new radio unit (RU) being connected to a front-haul network. The new RU determines its own Internet Protocol (IP) address based on its MAC address; and send a discovery message to all radio controllers in the front-haul network via a multicast address. The distributed RAN also includes a plurality of radio controllers communicatively coupled to the new RU via the front-haul network. Each of the plurality of radio controllers are configured to receive the discovery message and determine whether the new RU is assigned to the respective radio controller. Each of at least one radio controller, to which the new RU is assigned, establishes at least one configuration session with the new RU.
